Best for learning kana quickly

I tried other free kana learning apps but was always disappointed. This app groups the presentation of the kana by consonant, and the quizzes cover progressively more of the full table as you go, reinforcing both new kana and previously-learned kana at the same time. The quizzes test audio recognition, reading-to-kana, and kana-to-reading, as well as recognizing kana within words. With this app I was able to learn the entire basic hiragana table in a single evening. The flashcard-like quizzes move quickly enough without extraneous sounds or animations to drill yourself quickly. I am very pleased with this app and happily sent a donation. It is easy to quickly move between quizzes to focus on the kana you want to.
